摘要

采用浸泡法在20°C、25°C和30°C三种水温下对6种河流鱼类进行了爱德华氏菌感染实验。在20°C时，只记录了ayu Plecoglossus altivelis和amur catfish Silurus asotus的死亡率。而在25°C或30°C时，除鲤鱼鲤外，hakontribilodon hakonensis、tokiensis Tachysurus tokiensis和日本鳗鲡(Anguilla japonica)等其他鱼类均出现了死亡事件，阿玉、黑龙江鲶鱼和gibachi的累积死亡率较高(≥80%)。这些结果表明，在高水温时期，许多河流鱼类都有感染伊氏伊氏杆菌的风险。

Evaluation of Pathogenicity of Edwardsiella ictaluri to Riverine Fish Species Using an Immersion Infection Method

Experimental infection trials of six riverine fish species with Edwardsiella ictaluri were performed using an immersion method at three water temperatures, 20°C, 25°C, and 30°C. At 20°C, mortalities were recorded only in ayu Plecoglossus altivelis and amur catfish Silurus asotus. Whereas, at 25°C or 30°C, mortality events occurred in other species including Japanese dace Tribilodon hakonensis, gibachi Tachysurus tokiensis, and Japanese eel Anguilla japonica, except for common carp Cyprinus carpio, and high (≥80%) cumulative mortalities were recorded in ayu, amur catfish, and gibachi. These results suggest that many riverine fishes are at risk of E. ictaluri infection during periods of high water temperature.
